A 75-turn coil with a diameter of 6.00 cm is placed in a constant, uniform magnetic field of 1.00 T directed perpendicular to th

e plane of the coil. Beginning at time t = 0 s, the field is increased at a uniform rate until it reaches 1.30 T at t = 10.0 s. The field remains constant thereafter. What is the magnitude of the induced emf in the coil at the t=5s?

Answer:

The induced emf in the coil at the t = 5s is 6.363 mV

Explanation:

Given;

number of turns = 75

diameter of the coil = 6 cm

magnetic field strength = 1 T

new magnetic field strength = 1.30 T at t = 10.0 s

Area \ of \ coil = \frac{\pi d^2}{4} =  \frac{\pi *0.06^2}{4} = 0.002828 \ m^2

E.M.F = \frac{NA* \delta B}{\delta t}

Between 0 to 5 s, Induced emf is given as;

E.M.F = \frac{75*0.002828*(B_5-1)}{5}

Between 5 to 10 s, Induced emf is given as;

E.M.F = \frac{75*0.002828*(1.3-B_5)}{5}

Since the field increased at a uniform rate until it reaches 1.30 T at t = 10.0 s, the induced emf will also increase in uniform rate. And equal time interval will generate same increase in field strength.

B₅ -1 = 1.3 - B₅

2B₅ = 2.3

B₅ = 1.15 T

Thus, magnetic field at t = 5 is 1.15 T

E.M.F = \frac{75*0.002828*(1.3-1.15)}{5} = 6.363 \ mV

Therefore, the induced emf in the coil at the t = 5s is 6.363 mV

Sound waves with a constant frequency of 250 hertz are traveling through air at stp. what is the wavelength of the sound waves
Deffense [45]

Answer:

wave length is 1.2m

Explanation:

since formula of wave length is v/f

v(speed of sound in air at stp is 300ms^-1)

f(frequency 250hertz)

then wave length is 300÷250 which give 1.2m

Which jovian planet should have the most extreme seasonal changes? a. Saturn b. Neptune c. Jupiter d. Uranus
Maksim231197 [3]

Answer:

D). Uranus.

Explanation:

Jovian planets are described as the planets which are giant balls of gases and located farthest from the sun which primarily include Jupiter, Saturn, Uranus, and Neptune.

As per the question, 'Uranus' is the jovian planet that would have the most extreme seasonal changes as its tilted axis leads each season to last for about 1/4 part of its 84 years orbit. The strong tilted axis encourages extreme changes in the season on Uranus. Thus, <u>option D</u> is the correct answer.

Sort the length measurements in increasing order of magnitude from smallest to largest Drag each tile to the correct box Tiles S
wariber [46]

Answer:

Nanometer, micrometer, centimeter, decimeter, dekameter, kilometer

Explanation:

Given the following length measurement :

micrometer Kilometer decimeter centimeter nanometer dekameter.

Sorting in increasing order of magnitude from Smallest to Largest.

Expressing in terms of meters :

1 meter = 0.1 decameter

1 meter = 1 × 10^9 nanometer

1 meter = 1 × 10^2 centimeter

1 meter = 1 × 10^1 decimeter

1 meter = 0.001 kilometer

1 meter = 1 × 10^6 micrometers

Hence, arranging from Smallest to Largest :

Nanometer, micrometer, centimeter, decimeter, dekameter, kilometer
